The Chelsea 489ZLDAX-A5XK or 489ZLDAXA5XK is a 489 Series Power Take-Off Assembly built for 8-bolt manual transmission applications including Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing mounts directly to the 8-bolt aperture, eliminating the adapter plate and its associated leak path. Intermittent torque rating for the 489 Series is 250 lb-ft (339 Nm); shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output shaft is a 1-1/4" round with key. Shift is wire/cable mechanical. Internal components are common to the Chelsea 442 Series. Also referenced as 1450-489ZLDAXA5XK, CHE-489ZLDAX-A5XK, S-10111, WA20-08-7079, WA8D24X-A3RA, and TG8DM6508-A3KX. Call us to confirm proper fit for your transmission.
The Chelsea 489 Series is suited for aerial, vocational and municipal, utility truck, snow and ice removal, fire and rescue, and dump truck applications. The 489 Series features strong tapered bearings instead of needle bearings for greater load-bearing capability. Twenty-seven output options are available across the series, including Chelsea's 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios and shift options are offered across the line. The kit-style construction and parts commonality with the 442 Series make service straightforward. For detailed parts information, refer to the 489 Series Parts List (HY25-2442-M1_US) and the Chelsea Service Manual (HY25-6489-M1/US).
